beta (truncated)

Distribution beta(p, q, 0, 1) is stretched by stretch coefficient, then shifted to the right by shift. After that it is truncated to fit in [min, max] interval. Truncation is performed by discarding every sample outside this interval and taking the subsequent try.

For more details see beta().

beta(double min, double max, double p, double q, double shift, double stretch)

Description

Generates a sample of truncated Beta distribution.

Parameters

Name	Type	Description
min	double	The minimum value that this function will return. The distribution is truncated to return values above this. If the sample (stretched and shifted) is below this value, it will be discarded and another sample will be drawn. Use -infinity for "No limit".
max	double	The maximum value that this function will return. The distribution is truncated to return values below this. If the sample (stretched and shifted) is bigger than this value, it will be discarded and another sample will be drawn. Use infinity for "No limit".
p	double	The lower shape parameter > 0. Also known as alpha parameter.
q	double	The upper shape parameter > 0. Also known as beta parameter.
shift	double	The shift parameter that indicates how much the (stretched) distribution will be shifted to the right.
stretch	double	The stretch parameter that indicates how much the distribution will be stretched.

Result

Type	Description
double	The generated sample.
